Abstract
This chapter addresses met mast measurements for wind turbine wake research, where we tackle the matter by posing and answering three questions. By asking ourselves what the value is of met mast measurements for wake/aerodynamic research, we describe how met masts can be and have been used in aerodynamic research, accompanied by a number of illustrative examples. Second, we trigger the question how to obtain the highest quality in met mast measurements. In this respect, we have identified standardization in the measurement chain itself, the definition of success criteria and a good understanding between what is required on model side, and what is practically possible on the experiment side. Third, we wonder what have we learned from wind turbine wake measurements, where we describe in more detail some experiments, returning to the illustrative examples. These reflect upon quantifying power deficits of waked turbines, quantifying offshore wind farm wake effects and quantifying wake deflection of misaligned wind turbines.

Notes
- 1.
In the wind energy sector various equivalent naming exists: “met mast,” “meteo mast,” “meteorological mast,” and even “met tower” etc. We will use “met mast” throughout this chapter.
- 2.
At the time of writing, the GE Haliade X is the largest operational wind turbine in the world with a rotor diameter of 220 m and a rated power of 13 MW.

The references provided do not necessarily describe the offshore sites in the all the details but are closer connected to the topic of wake measurements. Clearly, further referencing is provided in these citations.
- 4.
We focus here on the content side of the matter, but one can also imagine the project management side of it. Many project proposal writers will recognize key performance indicators (KPI) as a request from subsidy providers, but also planning of the campaign and associated budgets. Again, we focus here on the content.

At the time of writing, the scaled wind farm has been dismantled and does not exist, anymore.
